[Zope-dev] FreeBSD, Zope and Plone

[Casey Duncan]

In my experience, python crashes on FreeBSD are due to the default thread=
=20
stack size problem exclusively. I run Python/Zope with complex sites all =
the=20
time (not plone tho) and once patched appropriately it never crashes unle=
ss I=20
cause it to.

There are two solutions to this IMHO:

1. Release a bug fix in Python (hasn't happened yet, but it has been disc=
ussed=20
several times)

2. Patch the FreeBSD python port. This is likely an excellent solution an=
d one=20
which could also solve the large file support issue simulaneously.

Unless PythonLabs tells me that 2.1.4 will fix these things, I will work =
on=20
making this happen this week. I will also see how plone behaves on my BSD=
 box=20
(firstly I guess).
